Be it known that I, Josnrrr B. NICHOLSON,

a citizen of the United States, residing at Steubenville, in the countyof Jefferson and State of Ohio,have nvented a certaln new and usefulImprovement 1n Machines for Manufacturing Ribbed and Hillside Pavil gBlocks, of which thefollowmg 1s a specifica t'ion.

This invention relates to the artof brick f or paving block manufacture,and has for its primary object the provision of a machine or mechanismdesigned to produce a peculiar style of paving blocks involving integralspacing ribs, together with a particu- 'lar design of blockadaptable'for hillside paving, orother various modifications susceptibleof being turned out by the device hereinafter described in detail andshown as V a part thereof in the accompanying drawmgs. I I g p In mypending application for patent on machine for manufacturing ribbedpaving block, Serial Number 847,304, filed June 25, 1914, there isdisclosed a knife or cutting memberheld stationary on a table, the blockmaterial to be operated on .being shoved over said knife, while in thepresent inven tion, which I consider is an improvement over the saidformer pending application;

thereis provided suitable mechanism whereby this cutting knife, 1n asomewhat modlfied form, is rendered movable either vertically orhorizontally, to effect itscutting function on the blocks presented insequence. In the accompanying drawings are shown the preferredembodiment of my invention, wherein I W V Figure 1 is a side'elevationof the complete assembled machine, showinga series of blocks in processof being operated on by the cutting elements: Fig. 2 is'a plan view ofthe same taken on the line 11-l1 of Fig. 1; Fig. 3 is a transversesection partly broken away and taken on the line 11llll of Fig. 1; Fig.4: is a similar view taken on the line IVIV of Fig. 1; Fig. 5 is a sideview in elevation of one of the vertically actuated cutting members,together with a portion .of the mechanism for operating same; Fig. 6 isa bottom plan view of a plurality of these cutting membersin securedposition on the carrying frame; Fig. 7 is an .endvie w lIl'QlGVZIlZlOIlof these cutting mem bers and supporting frame; Fig. 8 shows a finishedblock as turned out by the machlne 7 its supporting members.

The next succeeding block or blocks, which have already been subjectedto the beveling process, are thus shoved into position directly beneaththe vertically actuated knives 22 by the time the plunger has completedits forward stroke, at which period the wheel 25 will have arrived atthe end of the rail farthest removed from the elevated section. Duringthe last five inches in the total backward stroke of approximatelyfourteen inches made by said plunger the wheel 25 again ascends theinclined section of the railb and in so doing forces upward on the link2%, raising the spring connected end of the fulcrum lever 19, therebylowering the opposite end, and forcing down the carrier 21, causing theknives 22 to perform their function of forming the integral ribs on theblock or blocks positioned underneath, the offal dropping throughsuitableapertures provided in the table onto a conveyor belt directlybelow, not shown however.

Should I desire to dispense with the beveling feature of the machine,the cutting members 13 can be removed from their supporting structure12, and by substituting the form of knife 28 shown in Fig. 12 integralribs may be provided on the face of the blocks presented to thehorizontally movable cutting action of said knife, as actuated by thefulcrumed lever 1i and associated mechanism heretofore described indetail. It is further apparent that it is possible to dispense with atleast two of the knives 22 and form the integral ribsHB on one sideofeach block, and that said knives are susceptible of rearrangement tosuit variable conditions or styles of blocks to be turned out by themachine. Modification in the detail construction of the knives is alsopossible in the event of it being desired to produce various other formsof either brick or paving blocks, therefore I do not limit myrail, asshown in l ig. 1,-descending the inclmedsectmn, and: when=-said plungerhas-f self to the" eXactufo-rmation. here disclosed, fforaccomplishingthis result is as followsz Alt'cach forward stroke ofth'e'piston 2 the *wheel 25 will ride the rail 6, starting from butreserve-the privilege .of making such being turned out by this machine,and within the scope of the appended claims.
